Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Broadband Router with SRX. The Wireless-G Broadband Router 
with SRX will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and 
securely.
How does the Wireless-G Broadband Router with SRX do all of this? A router is a device that allows access to an 
Internet connection over a network. With the Wireless-G Broadband Router with SRX, this access can be shared 
over the four switched ports or via the wireless network, broadcast at either 11Mbps for Wireless-B or 54Mbps 
for Wireless-G. In addition, WEP encryption provides greater security opportunities while the whole network is 
protected through a Stateful Packet Inspection (SPI) firewall and NAT technology. All of these security features, as 
well as full configurability, are accessed through the easy-to-use browser-based utility.
But what does all of this mean? 
Networks are useful tools for sharing computer resources. You can access one printer from different computers 
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video 
games. So, networks are not only useful in homes and offices, they can also be fun.
PCs on a wired network create a Local Area Network. They are connected with Ethernet cables, which is why the 
network is called “wired”. 
PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the 
same wireless settings, within their transmission radius, they form a wireless network. The Wireless-G 
Broadband Router with SRX bridges wireless networks of both 802.11b and 802.11g standards and wired 
networks, allowing them to communicate with each other. 
With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet 
access—and even play games. All the while, the Wireless-G Broadband Router with SRX protects your networks 
from unauthorized and unwelcome users.
You should always use the Setup CD-ROM when you first install the Router. If you do not wish to run the Setup 
Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Wireless-G 
Broadband Router with SRX, set it up, and configure it to bridge your different networks. These instructions 
should be all you need to get the most out of the Wireless-G Broadband Router with SRX.
